4-Inch Lift Kit

The BDS Suspension 4-inch suspension lift kit is engineered to significantly upgrade the performance, capability, and stance of 2025 Chevrolet Silverado 1500 and GMC Sierra 1500 4WD Gas models. This comprehensive kit provides the necessary components to achieve a 4-inch lift, allowing for the fitment of up to 33-inch tires. This system utilizes a high-clearance design featuring 1/4-inch thick steel crossmembers and multipiece differential relocation brackets to enhance ground clearance and protect the undercarriage. The front suspension includes top-mounted strut spacers, CNC-machined ductile iron steering knuckles, and replacement tie rod ends that maintain ESC system compatibility. For the rear, a heavy-duty lift block is included to level the stance while retaining factory load capacity. The kit also incorporates sway bar drops, bump stop extensions, brake line brackets, and CV spacers to ensure proper geometry correction and component alignment. Customers can choose between various shock absorber options, including the NX2 Nitro Series or premium FOX 2.0 Performance Series shocks for the rear, and either a Strut Spacer or FOX 2.0 Performance Series for the front. The FOX 2.0 options offer enhanced performance with features like an impact-extruded aluminum body, application-specific valving, and an internal floating piston (IFP) monotube design for improved on-road handling and off-road capability. All kits come with the BDS Factory Protection Plus drivetrain warranty.
